Developer in plea deal over campaign donations

A major Boston developer is facing a $200,000 fine as part of a plea deal with federal prosecutors to bring an end to an investigation into illegal campaign donations he and one of his companies made to major Massachusetts political figures, according to court records.

Arthur Winn, 72, of Brookline is expected in US District Court in the near future to formally admit his guilt to charges that he secretly funneled thousands of dollars in donations to the campaigns of US Representatives Michael Capuano and Stephen Lynch, according to a plea agreement filed in court. There is no allegation of wrongdoing by Capuano and Lynch.
